Breaking news: Experts cite “concern” over polycarbonate baby bottles
Are certain plastic baby bottles dangerous? Readers of our new 3rd
edition (out in stores now) may remember our discussion of the safety
of polycarbonate baby bottles—and how a federal panel studying the
issue was about to weigh in on the issue.
Well, the results are in. Here’s the scoop:
An independent review panel assigned by the National Institute of
Environmental Health Sciences and the National Toxicology Program
weighed in on the toxic plastics debate last week. Their conclusion:
they have “some concerns” about chemical used to make polycarbonate
bottles, Bisphenol A (BPA), potentially causing neurologic and
behavioral problems in fetuses, infants, and children.
What does that mean for your baby and those baby bottles and sippy cups
sitting in your kitchen? Here are the most common questions parents are
asking, and our answers based on what we know.
Q. What the heck is BPA? Why is it dangerous?
Clear plastic baby bottles (as well as some food containers and water
bottles) are made of polycarbonate, which contains a chemical called
Bisphenol A (BPA). It is the BPA that makes the hard, clear plastic
bottles . . . well, hard and clear.
Here’s the rub: BPA’s chemical bond with polycarbonate breaks down over
time—especially with repeated washings or heating of the bottle. As a
result, BPA may leach out of the plastic bottle or sippy cup . . . and
into the liquid (that is, breast milk or formula). BPA has been used
since the 1950’s in a variety of products and we know that humans
ingest (and eliminate) small amounts of this substance on a daily basis
considering 95% of humans studied have it in their urine.
While most data BPA comes from animal research, studies show even
low-level BPA MAY be linked to everything from early puberty to breast
cancer, to attention and developmental problems. It’s hard to say that
humans will have the same health consequences, but there is certainly
enough concern that it deserves investigating the effects on humans.
The Environmental Protection Agency has set an “acceptable” or “safe”
level of daily BPA exposure to be 50 micrograms per body kilogram per
day. However, some scientists worry that humans may be exposed to up to
ten times that daily dose.
We wrote a detailed article on BPA and plastic baby bottles in our
newly revised 3rd edition of Baby 411. It is available online at our
website:

Q. Do we really know that these bottles are dangerous to humans?
No, we don’t. There have been no human studies on BPA—so far, researchers have only found problems in animal research.
There is a split opinion here among scientists. The same federal panel
that said it had “some concern” about behavioral and developmental
problems in babies also stated that links to other ailments like birth
defects and adult ailments were “negligible.”
That contrasts to the group of 38 scientists who last week called the threat from BPA as “significant.”
But the fact the federal panel said there were some concerns for the health of babies tipped the balance for us.
As a parent, we realize it can be hard to decide what to do when the
debate is so heated. As always, our mantra is “show us the science.” We
believe enough science is now in to recommend a change in course.
Q. Isn’t it a bit alarmist to say stop using these bottles?
The truth is we won’t know for YEARS if there is a human health
problem. And, it could be YEARS more before the government decides to
take some regulatory action.
Our opinion: if concerns exist today (and that is backed up by
reputable scientific research), then why not try to limit your baby’s
exposure to this chemical?
We suggest stop using polycarbonate baby bottles and sippy cups now.
Since there are quite a few BPA-free bottles on the market (see below),
we believe this is an easy call for parents.
Q. The Juvenile Products Manufacturer’s Association said plastic baby bottles are safe.
In a recent statement, the JPMA said the federal panels report on BPA “reaffirms the safety of plastic baby bottles.”
With all due respect to the fine folks at the JPMA, we’re not sure they
were reading the same report we did. If they did, they would note this
sentence: “The Expert Panel expressed some concern that Exposure to BPA
causes neural and behavioral effects.”

We realize you can argue that the panel didn’t call for the ban of
products with BPA. But, that’s NOT what the panel was asked to do. It
will now take years of debate among scientists, researchers and
politicians as to the best course to take with BPA.
For the record, Avent told us they believe their bottles are safe and pose no health threat to babies.
Q. Which bottles should we NOT use? Which ones are BPA-free?
Polycarbonate baby bottles make up about 90% of the bottle market. The
most common polycarbonate bottle is Avent’s Natural Feeding Bottle and
Dr. Brown’s Natural flow. But other major baby product companies like
Playtex and Gerber also make polycarbonate bottles.
See our website at baby411.com for pictures of bottles containing BPA:

Here are the alternatives that are BPA-free:
• Use glass bottles. Obviously, there is a risk of injury to baby or
mom if the bottle is dropped, so glass isn’t a perfect alternative.
• Use bottles made of opaque plastic. These bottles (made of polyethylene or polypropylene) do not contain BPA.
• Consider a BPA-free plastic bottle. Born Free makes a BPA-free clear plastic bottle (Newbornfree.com) sold at Whole Foods. But these cost about $10 each, twice the price of Avent bottles.
• Use a drop-in system. For example the Playtex Drop-in System is BPA
free (that is, the bottle liners do not contain BPA). Avent’s Tempo
liners are another example.

Q. Is there a way to tell if a bottle has BPA?
A. Unfortunately, it isn’t easy. Here’s a general guide:
BAD:
• Bottles that have a #7 on their recycling label most likely are made of polycarbonate (and contain BPA).
GOOD:
• Bottles that have a #2, #4 , #5 are made of polyethylene or polypropylene—these do NOT have BPA.
We call on the government to require disclosure of which bottles have BPA, so consumers can make an informed choice.
Q. What about sippy cups?
A. Basically, the same advice applies: avoid those made of polycarbonate. Sippy cups made of opaque plastic are fine.
Q. What about breast-pump collection bottles?
A. Again, avoid polycarbonate bottles (Avent Isis is an example) and
choose BPA-free options. For example, all of Medela’s bottles are made
from BPA-free plastics.
Q. I just bought $50 worth of Avent bottles. Are you saying I should throw them out?
A. Yes. We realize this in an inconvenience—but if you think about it,
buying replacement bottles would run only $50 to $100. When it comes to
safety, we think this is a worthwhile investment.
What if you don’t want to give up your polycarbonate bottles? While we
don’t recommend that option, to lower the amount of BPA that may leach
out, avoid heating the bottles in a dishwasher, microwave, or
sterilizer. And, toss out any baby bottles that are cracked. Again, we
believe the safest course is to replace the bottles with BPA-free
alternatives.
